INTERIOR COLLAR CAN Filed June 4, 1930 Patented Sept. 29, 1931 v UNITED STATES ATENT OFFICE ALFRED L. KRONQUEST, OF SYRACUSE, NEW YORK, .ASSIGNOR TO CONTINENTAL CAN COMPANY, INC., OF NEW YORK, N. Y A CORPORATION OF NEW YORK INTERIOR COLLAR CAN Application filed June 4,

The invention relates to new and useful improvements in metal containers and more particularly to a container that is easily opened.

In my prior application, SerialNumber 356,7d1, filed April 20, 1929, I have shown and described a container having a collar frictionally secured within the container body, which receives and holds the inverted in cover after it has been released by the rip strip.

An object of the resent invention is to provide means for a joining the ends of the lank or band formin the collar so that the end portions will be eld firmly in abutted relationl v A further object is to provide a connection of the above type for the ends wherein the metal at the outer face of the collar is so an disposedthat the collar is of uniform outside diameter throughout.

Referring to the drawings which show by way of illustration one embodiment of the present invention Fig. 1 is a verticalisectional view through a container, showing the collar in place.

Fi 2 is a lan view of the metal blank whic forms t e collar as it is not notched before folding.

:c Fig. 3 is an enlarged sectional view through the portion of the collar where the ends are joined, showing diagrammatically theis interlocking and overlapping of the The invention is directed broadly to means for joining the ends of the collar disposed within a rip strip type of container. The container consists of a body portion having its ends double seamed thereto. The body portion is provided with score lines adjacent the u per double seam which form a rip strip a apted to be torn away b a turning key to release the cover. The co lar is disfised with the container so as to project a ve the lower scere line. The collar is preferably held in the container bod by a ictional 'p between the collar and the body wall. his requires that the ends of the collar be firmly joined and held in abut- 60 ted relation. This joining is accomplished 1930. Serial No. 459,202.

by an interlocking and overlapping of the ends of the collar. One .of the end portions is offset and then bent back upon itself for a distance and again bent so that the end is substantially on a line with the first bend that is formed. This provides a housing between the two folded back portions for the other end. When the other end is inserted intothe housing and gri ped between its retaining walls an interloc 'ng and overlapping of the ends is accomplished wherein the ends cannot shift-laterally and slip h each other, but are held firmly in abutte relation. Therefore, the collar may be made slightly lar er in diameter than the inner diameter of the container and forced'into the container for a firm frictional grip. The blank or band is bent longitudinally upon itself before the ends are bent and shaped, so as to inset the upper portion thereof to facilitate reclosing.

Referring more in detail to the drawings, the improved container includes a body portion 1 which is preferabl cylindrical and of uniform cross-section t roughout. Each end of the body portion isfianged in the usual manner andclosing ends are secured thereto by double seam. The upper end 2 as shown in the drawings is secured to the. body portion 1 by a double seam 3. This upper end 2 has a central depressed portion providing a substantially vertical wall 4: directly in rear of the double seam. This central depressed portion is enlarged and the vertical wall 4 extends further down the inner face of the body portion of the container. This central depressed portion forms a recex 5. The body portion is provided with score lines 6 and 7. The score line 7 is located just beneath the double seam 3, the score line 6 is further down the container and a rip strip 8 is formed by these score lines provided with the usual means, whereby said ripstrip may be torn out thus releasing the end 2 from the container body. As described in the prior application noted before, this end may be reversed and placed in frictional engagement on the container body for reclosure of the same.

Located within the container body is a collar 9. This collar 9 has a portion 10 folded back upon the outer face of the collar. The collar 9 at its upper end is rolled at 11 into a false wire as shown in the drawings, and this provides a smooth upper edge for the collar. The collar is so proportioned that the outerdiameter of the folded back portion 10 is substantially the same or slightly greater than the inner diameter of the body portion of the container.

The present invention is directed particularly to the means whereby the ends of the collar 9 are joined so that when this collar is put under compression incident to the forcing of the collar into the container body the ends cannot shift laterally and slip by each other and thus become released. After the collar blank 9 has been longitudinally folded back upon itself to form the fold 10 as stated above one of the end portions is bent laterally at 12 to form an offset, the offset portion 13 is bent back on itself forming the portion 14. This portion 14 is again bent at right angles as indicated at 15 and this right angle portion 15 is so disposed as to engage the inner face of the shoulder formed by the offset 12. This end of the collar is again bent to provide a po'rtion 16, the portions 14 and 16 are spaced the thickness of the metal forming the collar, and the portion 17 of the other end of the collar extends into the housing formed by these space portions 14 and 16. There its end abuts against the right angle portion 15. It will be noted that the portion 17 on the left hand end of the collar as viewed in Fig. 3 is in alinement with the portion of the collar at the other side of the joining seam. It will also be noted that this portion 17 is confined between the portions 14 and 16 and held from lateral shifting movement. After the arts have been placed, then the seam is um ed so that these portions 14 and 16 firm y grip the end 17 of the collar. When the collar is inserted in the body of the container, it is put under pressure which forces the ends into contact with each other, and as it is crowded into the body for the tight frictional gri the collar is under compression. This orce, however, cannot in any- Wag disturb the seam joining the ends. The col ar portions are in alinement so that there is little or 'no lateral force applied to the collar at the seam. The overlapping parts cannot shift laterally as they are interlocked,

and therefore no slipping of one end by the other thus releasing the collar can occur. The ends of the folded back portions 10 are cut away as indicated in 18 and 19, see Fig. 2 so as to provide a space for the portion 16. The outer face of this portion 16 is in a line with the outer face of the folded back portion 10, thus it is that the collar on its outer face is of substantially uniform diameter throughout and the circumferential line of contact between the collar and the wall of the can body is continuous. The interfolded parts are of greater thickness than the collar but the parts of greater thickness are on the inner side of the collar.

The blank is cut away as indicatedat 20, so that the ends of the rolled portion at the upper end of the collars may be abutted.

While the invention is shown as applied to a collar having a head at its u per edge and also as having a folded-bac portion to inset the upper part of the collar from the wall of the container, it will be understood that the collar may be made in other ways.' The essential features of the invention reside in the construction, whereby the ends of the collar are overlapped and interlocked and firmly held in abutted relation when the collar is under compression. It will be obvious that minor changes in the shaping of the parts forming the interlocking of the ends may be made without departing from the spirit of the invention as set forth in the appended claims. T

Having thus described the invention, what I claim is new, and desire to secure by Letters Patent is l. 'A metal container comprising a body portion and ends secured thereto by seaming, said body portion having'score lines adjacent one end thereof, forming a rip strip for releasing the end, and a collar dis osed within the body so that the upper en thereof extends above the lower score line, one end of said collar being straight and the other end being bent upon itself to form a housing for said straight end, whereby said end portions of the collar are firmly held in abutted relation and prevented from shifting laterally and releasing when said collar is un- L der compression.

2. A metal container comprisin a body portion and ends secured thereto yv seaming, said body portion having score lines adjacent one end thereof, forming a rip strip for releasing the end, and a collar disposed within the bod so that the upper end thereof extends above the lower score line, one end of said collar bein straight and the other end of said collar set laterally to form a shoulder, said offset portion being bent upon itself to form space portions engaging said shoulder and ada ted to receive and house therebetween t e other end of the collar.

3.
